SAWING MACHINE'.

SPECIFICATION forming part of Letters Patent No. 271,454, dated January 30, 1883. Application filed August 25, 1882. (ModeL) To all whom it may concern:

Be it'known that I, JONATHAN HENDER- SHOT, of Shirtzville, in the county of \Virt and State of West Virginia, have invented a new and Improved Sawing-Machine, of which the following is a full, clear, and exact description.

The invention consists in combining certain parts of a drag-saw, as hereinafter described, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of my improved sawing-machine. Fig. 2 is a plan view, and Fig. 8 is a section on line 00 w of Fig. 1.

I make a suitable frame of two upright and parallel sides, a and I), connected by rods or ties c, and having feet (I, by which to fasten it to the floor or a bench with bolts, or to the ground With stakes, between which two sides the gate 6 is arranged to slide freely up and down, being raised by the winchfand cord 9 and lowered by its weight on the saw as it cuts its way in the wood. The gate is grooved at h to be properlyguided and controlled against the thrusts of the saw by studs ion the frame, which in this case serve for stops to limit the descent of the saw by the shoulders j of the grooves h lodging on them, and said studs i are adjustable up and down on the frame by the slotted shanks k and clamp-screws l, with which scales at are marked on.the frame, by which to set them for limiting the descent of the saw u as required, the saw being mounted at the ends on cross-heads 0, which slide on ways 19, attached to the gate, and itis connected by rod q with the crank-shaft 7', which is driven by a belt, 8, from a drivingwheel, t, to which the power may be applied by hand or by any other improved means; or if steam is to be used the belt from the crank-shaft of the engine may work directly onto a pulley on the a crank-shaft r.

The wood to be sawed is placed in the space u in the middle of the frame and traversed by the saw, where it is to be secured by the adjustable stops o, secured to the frame by clamp-screws w in such manner that they can be set with the square ends against the fiat sides of timber to be framed, so as to hold said sides square to the saw or at any angle, the stops being turned on as well as shifted along the clamp-screws.

The saw is to be detachably connected to the cross-heads by bolts 00 or other approved means, so as to be readily taken out for sharpeuing.

I propose to construct the machine in different sizes for use in shops, lumber-yards, andother places, according to the nature of the work.

For sawing logs in the woods the machine is to be so constructed that it can be readily lifted up and placed over the logs. The stops *5 in such case will be set without reference to the scales, being merely so as to arrest the saw and prevent it from falling after cutting through the log, and the stops 1) will be set against the sides of the logs to prevent the frame from shifting,and the power-wheels and belt may be suitably inclosedor cased to prevent accidents. I

Having thus described my invention, I claim asnew and desire to secure by Letters Patent- 1. The combination, with the gate having grooves h, of thestuds i,having slotted shanks k, the clamp-screws l, and the frame having scales m, whereby the limit of descent of the saw may he graduated, as described.

2. The combination of gage-stops 7170 with frame a b, saw'gate e, and saw a, the saw-gate having guide-grooves h and shoulders j, substantially as described.

3. The combination of the adjustable stops 1: with the frame a I) and saw a, substantially as described.

JONATHAN HENDERSHOT.
